Background technology
At present, along with the requirement of milling equipment to bearing is more and more higher, the use of high-accuracy and constant means of press seals bearing is also more and more extensive.The twelve high mill etc. that the company such as high precision mill, Beijing Si Dierluolin that MIT produces produces, all because the lubricating system of equipment self needs, requires as its bearing be equipped with must possess the constant voltage sealing property of 7KPa ~ 9KPa.But the performance entirety of domestic encapsulant is poor, and pressure limit required by the type bearing is less, so for the O-ring seal of every suit bearing, all need to go one by one in advance to test the magnitude of interference numerical value between O-ring seal lip external diameter and raceway, but limit by bearing arrangement, O-ring seal is arranged on after on bearing non-dismountable, go to test and calculate the magnitude of interference numerical value under constant pressure value requires in advance so need to design this pressure tester, thus guarantee that bearing possesses the constant voltage performance of 7KPa ~ 9KPa, foreign matter can be stoped to make bearing, cutting fluids etc. enter inside, and ensure the lubrication pressure of milling train inside, the loss and pollution that prevent from bearing oil from outflowing causing.
Summary of the invention
In view of the foregoing, the present invention proposes taper hole type bearing sealed ring pressure-bearing proving installation, and this pressure tester can detect the O-ring seal load performance of high-accuracy and constant means of press seals bearing.
The technical scheme that the present invention solves the employing of its technical matters is: taper hole type bearing sealed ring pressure-bearing proving installation, by taper hole type pressure chamber walls, gland nut, bearing sealed ring, scale screw rod, pushnut, screw-casing, taper hole type pressure chamber, O-ring seal, tensimeter and external pressure airduct composition, scale screw rod is arranged in taper hole type pressure chamber, one end of scale screw rod is fixed in taper hole type pressure chamber walls by the nut of scale screw rod and gland nut, bearing sealed ring is arranged on the other end of scale screw rod, about bearing sealed ring, end is separately installed with screw-casing and pushnut, O-ring seal is provided with between scale screw rod and taper hole type pressure chamber walls, external pressure airduct and tensimeter are arranged in taper hole type pressure chamber walls, described taper hole type pressure chamber is high precision taper hole, tapering is 1:30.
Because bearing sealed ring 3 is arranged on the scale screw rod 4 with scale mark, make it retreat on screw rod by turn nut, accurately can read the concrete axial location of bearing sealed ring 3 in pressure tester;
Taper hole type pressure chamber makes high precision taper hole, and tapering is 1:30.By turn nut, bearing sealed ring can being made along the accurately movement of scale screw axial, by reading the scale numerical value on scale screw rod, the inner diameter of the pressure tester corresponding to this position can be accurately calculated, i.e. pressure diameter D;
The internal pressure of whole proving installation is regulated by the magnitude of interference H controlled between bearing sealed ring lip external diameter and taper hole type pressure chamber inwall;
Proving installation, with tensimeter, can accurately read cavity pressure value;
By repeatedly recording the nut location on scale screw rod and the tensimeter registration corresponding to this position, the load performance curve of bearing sealed ring can be made;
The invention has the beneficial effects as follows: structure of the present invention is simple, and easy to operate, test result is accurate, without the need to changing other parts of pressure tester, the screw-casing only need changing different size just can do pressure-bearing test for the bearing sealed ring of different inner diameters size, and experimentation cost is lower

Embodiment
Below in conjunction with drawings and Examples, the invention will be further described: as Fig. 1, shown in Fig. 2 and Fig. 3, taper hole type bearing sealed ring pressure-bearing proving installation of the present invention, by taper hole type pressure chamber walls 1, gland nut 2, bearing sealed ring 3, scale screw rod 4, pushnut 5, screw-casing 6, taper hole type pressure chamber 7, O-ring seal 8, tensimeter 9 and external pressure airduct 10 form, scale screw rod 4 is provided with in taper hole type pressure chamber 7, one end of scale screw rod 4 is fixed in taper hole type pressure chamber walls 1 by the nut of scale screw rod 4 and gland nut 2, bearing sealed ring 3 is arranged on the other end of scale screw rod 4, bearing sealed ring about 3 end is separately installed with screw-casing 6 and pushnut 5, O-ring seal 8 is provided with between scale screw rod 4 and taper hole type pressure chamber walls 1, taper hole type pressure chamber walls 1 is provided with external pressure airduct 10 and tensimeter 9, described taper hole type pressure chamber 7 is high precision taper hole, tapering is 1:30.
Because bearing sealed ring 3 is arranged on the scale screw rod 4 with scale mark, make it retreat on screw rod by turn nut, accurately can read the concrete axial location of bearing sealed ring 3 in pressure tester;
Taper hole type pressure chamber 7 makes high precision taper hole, and tapering is 1:30.By turn nut, bearing sealed ring 3 can being made axially accurately mobile along scale screw rod 4, by reading the scale numerical value on scale screw rod 4, the inner diameter of the pressure tester corresponding to this position can be accurately calculated, i.e. pressure diameter D;
The internal pressure of whole proving installation is regulated by the magnitude of interference H controlled between bearing sealed ring 3 lip external diameter and taper hole type pressure chamber 7 inwall;
Proving installation, with tensimeter, can accurately read cavity pressure value;
By repeatedly recording the nut location on scale screw rod 4 and the tensimeter registration corresponding to this position, the load performance curve of bearing sealed ring 3 can be made;
After the gases at high pressure of external pressure airduct 10 enter taper hole type pressure chamber 7 and reach certain pressure, can flow out from the lip position of bearing sealed ring 3, and concrete force value accurately reads by the tensimeter 9 that proving installation is external.By regulating the position of the pushnut 5 be arranged on scale screw rod 4, can continue to increase or reduce the magnitude of interference H between bearing sealed ring 3 lip external diameter and taper hole type pressure chamber inwall 1, thus change the pressure value of proving installation inside.When the reading of tensimeter 9 reaches 7KPa and 9KPa respectively, read the concrete scale numerical value of pushnut 5 when this two pressure, the magnitude of interference H numerical range that bearing sealed ring 3 lip is corresponding when this force value can be accurately calculated.These two numerical value can be used as two limiting figures of the magnitude of interference between bearing outer ring ball track and bearing sealed ring 3 lip.By being worked within this scope by bearing outer ring ball track diameter, accurately can ensure that the sealing pressure maintaining performance of every suit bearing is within the 7KPa ~ 9KPa required by client.
In addition, the present invention also can be used to calculate different structure O-ring seal load performance curve, namely install after O-ring seal, by turn nut, O-ring seal can be made to prolong the accurately movement of scale screw axial, by reading the scale numerical value on screw rod, the magnitude of interference between O-ring seal lip external diameter and pressure chamber inwall can be accurately calculated; By repeatedly recording the tensimeter registration corresponding to nut location on scale screw rod and this position, thus provide basic data for the pressure-bearing curve of the O-ring seal drawing different structure.
